Title: Power supply system for stabilizing variable output
Inventor: USUDA MASAMICHI
IPC: G05F1/00
Filed: 1981-07-01
Abstract: PURPOSE:To reduce the loss of electric power from a zero output through the maximum output, by incorporating a phase control system also into a secondary power supply circuit. CONSTITUTION:A phase control system is incorporated into a secondary power supply circuit 1, and this circuit 1 has an operation after the output is set less than V1-Vref2. In this connection, the comparison reference voltage Vref1 of a comparison amplifier OP1 is set slightly higher than the comparison reference voltage Vref2 of a comparison amplifier OP2. Thus the power loss of a serial control transistor TR1 is equal to (Vref2X output current) and to (Vref1X output current) when the output voltage of a main power supply device is higher and lower than V1-Vref2 respectively. Thus the loss of electric power can be reduced over the entire output variable band of the power supply device.

Filed: 1992-04-22
Abstract: PURPOSE:To quicken the circuit operation by increasing the response to synchronization with respect to the PLL circuit outputting a clock signal synchronously with a phase of an input signal. CONSTITUTION:A phase coincidence detection means 2 detects the coincidence between a phase of an input signal with which the means 2 is synchronous and a phase of a succeeding input signal with which the means 2 is to be synchronous and when the phase coincidence detection means 2 detects the coincidence of the phases, an operation permission means 3 gives an operation permission to a changeover means 1. Thus, the changeover means 1 selects the input signal to be synchronized next from the current synchronizing input signal for a signal to be outputted to a phase detector (PD) of the PLL circuit. Since the timing when the changeover means 1 executes this changeover is a point of time when the phase of the input signal synchronized at present and the phase of the input signal to be synchronized next, no out of synchronism takes place in the PLL circuit.
